Application filed October is, 1918. Serial no. 258,730.

To all whom it may concern:

Be it known that I, EDWARD H. FRIGKEY, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in a Crusher, of which the following'is a speci-' lication.

This invention relates to improvements in rotary heaters, and it consists in the novel arrangement. construction and combination of parts, which is required to make a complete operative and unique machine, the details of construction will be fully hereinafter described and set forth in the claims.

The object of my invention is to construct and assemble a machine in which the material or articles to be crushed and broken is fed into a hopper and brought in. contact with rapidly rotating hammers or pounders which break the material into small particles, and permits the small or crushed material to pass out through a sieve or perforated bottom.

A further object of my invention is to provide an axially mounted hammer sup"- porting head in which is pivotally mounted a plurality of sets of hammers, the eriph eral ends designed to be brought against the material with great pounding force, crushing action caused by the centrifugal action of the rotating head.

A still further object is to provide a breaker plate in close proximity to the peripheral path of the hammers between which the material is crushed.

A still further object is to provide suflicient means whereby the material to be crushed is cut and sheared by the co-operation of the rotating hammers.

Another object of my invention is to arrange the machine in general so that the several parts are easily assembled and access had to the parts with little ease.

Figure 1, is a side view of my complete invention.

Fig. 2, is an end view of the same. Fig. 3, is a central sectional view.

Fig. 4, is a central cross sectional view.

The general construction of my invention consists of a housing comprising two side walls 5, a front wall 6 and a rear wall 7; the upper portion is formed in a hopper 8 in which the material to be crushed is inserted.

The proper inclination is given to the hopper by inclining the upper portions-of the side walls 5, and forming onthe wall 7 an inwardly and downwardly inclined partition 9. which terminates at a cross bar 10 running through the housing, and attached to the inside of the wall -6 is a hopper plate 1]. having positioned on'the under face of its downwardly extending portion a series of removable cutter edges 11 for the purpose hereinafter described.

The side walls are equipped with detachable heads12 in which is axially mounted a shaft 13. On this shaft and extending from head to head is firmly fixed a hammer supporting head 14, the same having circumferential grooves 15 in which are pivotally mounted by pins 16 hammers or-pounders 17. The hammersare a plurality in number and arranged in pairs, each being free to operate independent of the other, the outer peripheral ends are bent outwardly at right angles forming a hammer or contact head 18 whllch exerts a pounding blow on the materia v These hammers exert-a. pounding action on the material by purely centrifugal action caused by the rapid rotation of the shaft 13, and on account of the freedom, the hammers have a certain amount of rebound when con; tacting with the material.

The shaft 13 is rotatably' supported in bearings 19 mounted in the heads 12 and said bearings consist of a ball race one secmaterial fed into the hopper will receive a cutting or shearing action between the cutter edges 11 and the transverse edges of the rotating hammer heads 18 and is thereafter subjected to a crushing process between the breaker plate 24' and the aforesaid rotating hammer heads. Excessive wear of the cutter edge is materially lessened by placing the cutter lates on the under face of the downwar y extending portion of the hopper plate 11, as clearly shown in Figure 3 of the drawings.

Beneath the centrifugal hammers is located a sheet of perforated or reticulated material 26 the same being supported on a frame 27 properly regulated and adjusted by the wedges 28, through this plate the crushed material is sifted, and the sifted material is delivered on a conveyor of any construction located beneath the machine,by which it is carried to a depository, the conveyor structure being nothing new it is not shown.

The housing is supported on a hinge 29 by which the machine may be tilted over in order that access may be had to the under part when found necessary.

The ball bearing mechanism in which the shaft is mounted is firmly clamped in members 3O controlled by the bolts 31.

This construction of crusher is especially designed for crushing corn on the cob and feed stuffs of any nature, and by said machine the cob of the corn is broken up or crushed into small particles.

The most essential feature of the invention is the construction of the hammers, the cutters associated therewith, and the arrangement' of the component parts.

Having fully described the construction of my invention what I claim is: g

1.- A rotary beater of the class described 30 comprising a housing, a rotating hammer supporting'head, a plurality of sets of hammers having a cutting head pivotally con nected to said supporting head, a detachable breaker plate against which the material to be crushed is brought in contact, and a removable cutter extendin substantially in the direction of rotation o and cooperating with the contact heads of the hammers to cutand shear the material before it reaches the crusher head.

2. A rotary beater comprising a housing, a shaft axially mounted therein, a hammer supporting head firmly attached to said shaft, and having a plurality of hammers, a removable breaker plate in close proximity to the peripheral radius of the hammers, a removable cutting edge positioned on the under face of a downwardly extending portion of said housing and cooperating with the hammers to cut the material before it reaches the breaker plate, and a sieve beneath the hammers.
